When it comes to pregnancy nutrition, most women know to take folic acid and iron. Choline, however, rarely gets the attention it deserves despite being one of the most critical nutrients for foetal brain development, healthy pregnancy and maternal mental health.
Research consistently shows that most pregnant women aren't meeting their recommended choline intake and that gap matters. Here's what choline does, why it's important at every stage from preconception to postpartum, and how to make sure you're getting enough.
Choline is an essential nutrient most pregnant women don't get enough of.
It supports foetal brain development, methylation, egg quality and maternal mental health.
Needs rise across the perinatal period highest during breastfeeding (550mg/day).
Eggs (with the yolk) are the most practical food source; plant-based diets often fall short.
Most prenatal vitamins contain little or no choline check your label, and discuss with your practitioner.
What Is Choline?
Choline is an essential nutrient the body can make in small amounts but not enough to meet its full needs, especially during pregnancy and lactation. It's involved in cell membrane structure, fat metabolism, neurotransmitter synthesis and, critically, methylation a biochemical process affecting gene expression, DNA repair and nervous-system function. That's why it matters across the entire perinatal period.
Choline and Preconception Health
Choline is a key methyl donor, supporting the methylation that influences gene expression and DNA repair both linked to egg quality and embryo viability. And because the neural tube (which becomes the brain and spinal cord) closes within the first 28 days of pregnancy often before you know you're pregnant building choline stores before conception means your body is ready from the very start.
Choline During Pregnancy
This is where choline's role becomes most pronounced.
Foetal brain and neural tube development: choline supports healthy development of the foetal brain, particularly the hippocampus (memory, learning, emotional regulation). Research links adequate maternal choline to proper neural tube closure and a reduced risk of neural tube defects.
Cognitive development that lasts: studies suggest adequate choline in pregnancy may have a measurable, lasting positive effect on a child's memory and attention.
Placental function and foetal growth: choline supports nutrient transport and the cell-membrane formation that rapid foetal growth demands.
Gene expression and pregnancy outcomes: as a methyl donor, choline helps regulate gene expression; research has explored links to a reduced risk of complications including preeclampsia.
Choline in the Postpartum Period
The need doesn't stop at birth, if anything, breastfeeding raises it.
Maternal mental health: choline is a precursor to acetylcholine (involved in mood and cognition); adequate levels may support maternal mental health postpartum.
Breastfeeding and infant brain development: choline is concentrated in breast milk from the mother's stores, which is why breastfeeding women have the highest recommended intake of all.
How Much Choline Do You Need?
Choline needs shift at every stage and most prenatal vitamins don't cover them. If you're planning, pregnant or breastfeeding, it's worth reviewing your intake with a naturopath or GP who works in women's health.
Stage |
Recommended Daily Intake |
Non-pregnant women |
425mg/day |
Preconception |
425mg/day (minimum) |
Pregnancy |
450mg/day |
Breastfeeding |
550mg/day |
Some researchers argue these may underestimate the optimal intake in pregnancy (with intakes closer to 930mg/day suggested for foetal brain development) — an evolving area worth discussing with your practitioner
Best Food Sources of Choline
Food |
Approximate Choline |
Beef liver (75g) |
~290mg |
Eggs (2 whole, with yolk) |
~250mg |
Salmon (85g) |
~190mg |
Chicken breast (85g) |
~72mg |
Broccoli (1 cup, cooked) |
~63mg |
Edamame (½ cup) |
~60mg |
Milk (1 cup) |
~38mg |
Chickpeas (½ cup) |
~35mg |
Eggs are the most practical everyday source a single whole egg (yolk included) provides ~125mg, and the yolk is where virtually all the choline lives. For plant-based diets, reaching adequate choline through food alone is much harder, so supplementation is worth discussing with your practitioner.
"Choline is one of the most important nutrients in pregnancy and one of the most overlooked. It deserves a place alongside folate, iron and omega-3s."
Does Your Prenatal Vitamin Cover Your Choline Needs?
Most standard pre-natals either don't include choline, or include it well below the 450–550mg recommended in pregnancy and lactation one of the most overlooked gaps in prenatal supplementation. Check your label; if choline isn't listed (or is low), discuss additional supplementation with your naturopath or GP.

Frequently Asked Questions
Is choline safe to supplement during pregnancy?
Choline is considered safe and well-tolerated in pregnancy and breastfeeding but always discuss supplementation and dosing with your healthcare provider.
Can I get enough choline from food alone?
It depends on your diet. Women who eat eggs daily and include oily fish (and occasionally liver) may meet their needs through food; research suggests most don't reach 450mg/day through diet alone.
Why isn't choline in most prenatal vitamins?
It's a bulky nutrient meaningful doses need a large capsule or a separate supplement, so many manufacturers leave it out. Check your label. Whole Health Studio's preconception, pregnancy and breastfeeding support contains choline.
What happens if choline intake is low during pregnancy?
Low intake has been associated with increased risk of neural tube defects and altered foetal brain development, and with fatigue and low mood for the mother.
Does choline cause side effects?
At recommended doses it's well tolerated. Very high doses can cause a fishy body odour or nausea, but these aren't typical at standard supplementation levels.
